KTuner V2.0 ECU Flash Tuner - Honda/Acura

You're tired of dragging a laptop to your car every time you want to switch maps or pull datalogs. The KTuner V2.0's a standalone handheld ECU tuner with a 5-inch touchscreen that plugs into your OBD2 port and does everything, flashing tunes, monitoring live data, storing datalogs, without a computer. You write your tune in the KTuner desktop software on your laptop, push it to the V2.0 over USB, then you're flashing tunes from the handheld whenever you want. No laptop bungee-corded to your passenger seat, no cables across your dash, no hassle. The V2.0 stores your factory tune plus multiple custom maps on the device so you can switch between a conservative daily map and an aggressive 93 octane map right in your driveway in about two minutes.

Here's Why You Want the V2.0 Instead of Just the Cable

KTuner makes a basic flash cable that's cheaper than the V2.0. That cable works fine but you need a laptop every single time you want to flash a tune or check data. The V2.0's different, it stores all your tunes on the handheld and it's got a full digital dash that runs while you're driving. You're looking at coolant temps, intake temps, AFR, fuel trims, knock counts, boost pressure (if you're turbocharged), whatever parameters you care about, all on the 5-inch screen. No separate gauges, no laptop propped on your dash. The screen's also got configurable layouts so you can set up different gauge clusters for street driving vs. track use vs. datalogging pulls.

One Device Locks to One ECU at a Time

Once you register the V2.0 and flash an ECU with it, the device locks to that ECU. You can't hand it to your friend so they can tune their car, it won't work. If you need to move the V2.0 to a different car, you flash your current ECU back to stock using the unlock function, then you can pair the V2.0 with the new ECU. One device, one ECU at a time. That's how KTuner's licensing works so if you're planning to tune multiple cars, you need multiple KTuner devices. Plan that out before you buy.

Stores 1,000 Datalogs On the Device

The V2.0 holds up to 1,000 datalogs on the handheld. You're doing street pulls, the device's recording everything, AFR, timing, knock, fuel pressure, whatever you've got sensors for. Later you pull the logs into the desktop software, review what the motor's doing, make your adjustments, push the revised tune back to the V2.0, and flash it. The whole tune-test-review loop stays clean and you're not texting your tuner blurry phone pictures of your AFR gauge. Professional tuners love this because they can hand a client the V2.0, tell them to do some pulls, and get actual usable datalogs back instead of "yeah it felt good."

RGB Shift Lights and Bluetooth

The V2.0's got five programmable RGB LEDs across the top. Set your shift point, configure warning thresholds for coolant temp or oil pressure, adjust the brightness. They work as a peripheral shift indicator when you're looking at the screen for your gauge layout. The unit's also got built-in Bluetooth so you can push live KTuner data to third-party display apps on your phone or tablet if you'd rather run data that way. Some people mount their phone on the dash and use it as a secondary display while the V2.0's tucked away somewhere.

Pass-Through Flashing if You Need It

If you're deep in a tuning session and you're making rapid back-to-back map changes, you can use pass-through mode to flash the car directly from the desktop software while the V2.0's still connected. You're getting the best of both, standalone convenience when you're out on the street, full desktop control when you're in the shop tweaking tables. Most people use the handheld 90% of the time and pass-through when they're really dialing something in.

Works with These Honda and Acura Models

KTuner supports a wide range of Honda and Acura platforms from the mid-2000s through the mid-2020s. The short version: if you're on a Civic, Accord, Fit, S2000, CR-V, HR-V, ILX, TLX, TSX, RSX, or most other Honda/Acura models, there's a good chance you're covered. Check the full compatibility list on KTuner's website before ordering if you're on an edge-case year or trim. Some models need specific firmware versions and some ECUs aren't supported at all. Don't assume your car's compatible, verify it first.

Get the Most Out of Your Tune

Tuning doesn't make power by itself, you need supporting mods to give the tune something to work with. If you're tuning a naturally aspirated K series, you're going to want a cold air intake and a header to actually see gains. If you're tuning a turbocharged 1.5T or 2.0T, you're looking at downpipe, intake, intercooler, and possibly upgraded fuel system components depending on how much boost you're running. The KTuner lets you adjust fuel, timing, cam angles, boost control, and all the tables that make those mods actually work together. Without the hardware, the tune's just optimizing a stock setup and you're leaving power on the table.

Note: All KTuner sales are final once the product's been received. We can't accept returns on tuning devices because of licensing and the nature of ECU tuners, once you've registered the device and flashed an ECU, it's used. Confirm your car's compatible before you order. If you're not sure whether KTuner supports your specific year/trim/ECU, contact us before you buy or check KTuner's compatibility list on their website. Don't guess, verify compatibility first or you're stuck with a device that won't work on your car.
